Specification of Letters Patent.

Application filed December 17, 1913. 1 Serial No. 807,297.

To all whom it may concern:

Be it known that LDAVID .T. MATTH W, a citizen of the United States, residing at Tacoma, in the county of Pierce and State of l/Vashington, have invented certain new and useful Improvements in Planing-Macation.

The object of this invention is to provide chines, of which the following is a specifia machine for jointing and planing lumber which will be especially adapted for small shops in which space is limited and in which it is frequently desirable and necessary to dress smallquantities of lumber in It isone of the objects of my invention to,

provide a machine in which a rotary cutter is so disposed with respect to jointer beds and a planing table as to be operable on ma terial disposed on either the bed or the table,

it being a special feature of my invention to provide independent adjustment for the 12 are ournaled in the sides 1 and 2 and 011 beds.

adjustable planing table, movable toward or from the rotary cutter, and having a remov-' able section for egress therethrough of chips and dust from the cutter when thelatter is utilized in jointer work.

A further feature of noveltyjconsists in the provision of stookholding meansfadjacent the cutter for holding stock down on the table 'to relieve the knives of the cutter )rovide an im )roved. 'ointer' 'a 'e whereb jointing'operation on the edges of the stock may be performed at any desired angle. 7

A still further objectis to provide jointer beds which may be removedfrom an 0perative to an inoperative position when it is desired to do planing work of an extensive character.

Other features and objects of the invention will be more particularly pointed out in and by the appended claims. I

In the drawings: Figure 1 is'a view in side elevation of a planing and jointer machine embodying oneform of my invention.

Fig. 2 is a view similar to Fig. 1, looking from the opposite side of the machine, show- A further feature consists in providing an ing one of the j ointer beds swung into an inoperative position. Fig. 8 is a plan view with both of thejointer beds in an operative position. Fig.- 4 is a longitudinal central sectional view of themaohine shown in Fig. 1' with the j ointer bed shown in an operative position. 5+5 of Fig.

As illustrated, the device of my invention includes a main-supporting frame comprising side members 1 and 2 which are suit-- ably braced and connected by transversely disposed rods 8. Bearings 4 and 5 are provided for a main shaft 6 on which a rotary cutter 7 is non-rotatably mounted. The drive shaft 6 extends outwardly beyond the bearing l where it is journaled in a bearing Patented Oct. 31, 1916.

Fig. '5 is a sectional view on line 8, mounted upon an arm 9 extending from their-outer endsI mount gear wheels 13 and. 14: for direct drive by means of a gear wheel15, with which the'wheels 13 and 1 1 mesh. i T

The bearingsfor the driven feed rolls .11 and 12 consist of box-portions formed in the side frame members 1 and 2 and bearing caps 16 and 17 which fit in suitable recesses in the side frame members 'l and 2, as will be clearly seen by reference to Fig. 4. Springcontrolled yokes hold the caps 17 down onto the rollers 11 and12,'and as shown, said yokes comprise bolts 18 and 19 passing through the caps 16 and 17 and connected at 22 and 23 are interposed between the bars 20 and 21 and the side frame members 1' and 2, to yieldingly hold the'driven rollers 11 and 12 in the position shown.

The gear wheel 15 is loosely mounted on the drive shaft 6 and is shown formed integral with a belt pulley 24 which is connected by a belt 25 with an idler 26. Idler their lower ends by bars 20 and 21. Springs 26 is mounted up'onastud shaft 27, se-

curedto frame member 1, as indicated at 28.

Idler 27 is formed integral with an idle pulley 29, mounted on stud shaft 27 and connected by a belt 30 with a pulley 31,'which latter is keyed upon the drive shaft 6. From the foregoing description of this portion of the transmission, it will be seen that a reduced speed train is provided for transmitting rotary motion to the driven feed rollers from thepulley 31.

When the machine is not to be operated as a planer, the arrangement is such that the feed rolls 11 and 12 will not be driven but when the machne is to be used for planing, the feed rolls 11 and 12 will be driven.

The belt 25 is tight on pulleys 24 and 26 but the belt 30 is loose on pulleys 331 and 29. I provide belt-tightening means which may consist of a rocking or adjusting shaft 32, mounted'in the side frame members 1 and 2 and provided with adjusting and locking means which is shown in the form of a lever 33. The lever 33 is provided with a manually operable dog 34 for engagement with a toothed segment 35, as will be clearly seen by reference to Fig. 2. A tightener pulley 36 ismouned upon an arm 37 which is secured to rock shaft 32 so that when it is desired to use the machine as a planer, the tightener pulley 36' can be adjusted to the position shown in Fig. 1 so as to transmit driving power from pulley 31 to pulley 29, and therethrough to pulley 24. If it is not de sired to use the machine as a planer, the pulley 36 will be adjusted to the right of Fig. 1 to free the belt 30 from driving frictional engagement with pulleys 29 and 31.

Below the rotary cutter 7 and between the side frame members 1 and 2, I adjustably mount a planer table which GOIIIPTISG'S' a table proper 38 having downwardly extending supporting sides 39. The sides of the table may be braced by rods 40, as shown more particularly in Fig. 4. I also slot the table sides at 41 to provide spaces for operating' mechanism for the table which will be presently described. In the table proper, of the table structure, I rotatably mount idle feed rolls 42 which are disposed in vertical alinement with the driven rolls 11 and 12 so as to coact therewith in engaging the stock on opposite sides and advancing the same beneath the cutter. Immediately below the cutter 7 I provide the table proper,- 38, with a removable section 43' which extends transversely of the table and parallelwith the axis of the rotary cutter 7 and which is preferably dove-tailed for longitudinal sliding movement into and out of position, as clearly shown at 44 in Fig. 4. VVhe'n the machine is not being used as a planer, and is being used as ajointer', removal of the section 43 provides an opening in the table 38 for passage therethrough of chips and dust from the cutter 7. WVhen the removable sec tion 43 is in place, it provides a flush sun face for the table 38, as will be seen by ref A supporting bearing bar 46, is connected with the side frame members 1 and 2, as indicated at 47, and screw-rods 48 are jour naled at their ends in the bar 46, as indicated at 49. Bearings 50 and 51 are provided'on the side frame members 1 and 2 in which the upper ends of the screw-rods 48 are'journaled. Bevel gears 52 are mounted on the upper ends of the screw or adjust ing rods 48 and said bevel gears mesh with bevel gears 53, mounted-on a shaft 54 which is suitably j ournaled at its ends'in the frame members 1 and 2. An adjusting hand wheel 55 is shown mounted upon one end of the shaft 54. Portions 56, of the side of the table, have threaded engagement with the adjusting rods 48- sothat upon rotation of said rods the table will be elevated or de= elevated in accordance with the direction of rotation imparted to the hand wheel 55.

As stock is fed through between the two sets of idlers and feed'rolls, beneath the rotary cutter, it may be inclined to buckle, as a result of being warped, or for other reae sons, sothat there will be a pressure against the knives of the rotary cutter, in addition to the cutting action performed thereby. Furthermore, when the stock is advanced through the planer in the direction of the arrow shown in Fig. 4, and has been released from rollers 11 and 42, the terminal end might tilt up against the knives in a highly objectionable manner, if the free or projecting end were not held so as to cause the stock to seek engagement withthe table 38. I provide means for avoiding this objectionable-action on the knives of the cutter, which means will now be described.

A shaft 56 is journaled in the side frame members 1 and 2, and is provided with an operating handle lever 57. whereby the. shaft 56- may be locked in any adjusted position. A cam 58 is mounted on shaft 56 and is adapted to be adjusted into bearing engagement with the upp'er'face of the stock in its will be readily seen from the foregoing that pressure by the cam 58 will serve to hold the stock against the table,- or onto'the feed rolls 42 so that it cannot buckle and exert an objectionable pressure against the knives of the cutter. The cam 58 will also hold the terminal end of the stock from objectionable pressure engagement with the knives of they cutter after the terminal end has passed the rollers 11 and 42.-

As before stated, it is one of the features of my invention to combine in a planing machine, a jointer, in sucli' a novelmanner that the rotary cutter will serve either for jointing or planing operation. 2 A

7 As illustrated, jointenbed supporting frames, 59 are disposed above the planer table 38 andon opposite sides of the rotative axis-of the cutter 7 Inasmuch as the passage between the pairs of feed rolls. It

jointer frames and the beds carried thereby, areboth identical in construction and operation, only one need be described in detail.

It will be seen by reference to Fig. 2, that the supporting frame 59 comprises lateral frame members 60 connected by transversely disposed frame members 61 and 62. In the lateral frame members 60 I provide dlagonal guide ways 63 for slidable engagement by" jointer bed guides 64. The jointer beds are indicated at 65 and are connected with guides 6% as indicated at 66. It will be seen by reference to Fig. a, that as the bed 65 is shifted in its guiding engagement with its supportmg frame, it will be elevated, and

m the present construction, moved toward the cutter 7'.

a in Fig .i.

I provide means for adjusting the'beds 65, independently of each other, so that they can be adjusted into a coincident plane with respect, to each other, or into chiferent planes. Theymay be adjusted into different planes to compensate for warp or mto a coincident plane, for omter work;

Each bed-651's provided with a bracket 67 through which an adjusting threaded rod 68 extends. The transverse member 62 carries a bearingbracket 69 in which the adj using rod 68 1s ournaled. A m ter gear 70' on adjusting rod 68 is held into mesh with a miter gear 71, by bearing 69. It will be noted that the adjusting rod 68'is disposed at an angle coincident with the angle of the guides 6 and the guide way 63. Miter gear 71is mounted upon a shaft 7 2 which is journaled in bearings 73 and 7e, and

which is provided with a hand wheel for rotably adjusting the shaft, as indicated at 75. I I

If it is desired toplane a limited amount of stock, the machine canbe utilized as a planerwhen it is in theadjustment shown If, however, there is a considerable amount of planing to do, I provide for adjustment of one jointer bed 65 out of an operative position so as to facilitate the use of the machine as a planer.

As shown, one supporting frame 59 for the jointer beds is hinged, as at 76,, to side frame member 1 so that it can be swung upwardly from a horizontal to a substantially vertical position. The bed 65 may be provided with an opening through which the end of a supporting rod 77 maybe projected, as indicated at 78, so as to hold the beds in the upright position shown in Fig.

2. In order to brace the arm 9, I bracket the frame structure, as indicated at 79, and I prefer to pivot the rod 77 on 79, as indicated at 80. Of course it will only be necessary to swing up one of the beds, and lock it in a swung position, but it will be readily seen that the same device may be applied to swing up the remaining bed and lock'it in an noperative position.

In order to do joining work, or in other 6 words, in order to dress the edges of lumber,

it is necessary to have the jointer beds ad justed to the desired horizontal alinement with respect to the rotary cutter, and it is also necessary to support the stock in dressing the "edges thereof: I provide animproved form'of jointer gage which I will now describe in detail.

As illustrated, my improved jointer gage comprises a] base gage member 81, and'an adjustable gage member 82. The base gage member 81 may be provided with an extension 83, slotted at 8%, foradjustment on one of the beds 65 by means such as a'setscrew S5. The base gage member overhangs the rotary cutter and extends over, and may, if,

desired, rest in supporting relation with the I 7 remaining bed 65. t I

At 86, I cut away the base gage member 81 to permit the same to extend over the cutter free ufrom engagement with the slotted bar 93. The slottedbar 93 is shown connected with lug by a bolt 94:, and with the standard 91 by a bolt 95.

It will be seen from the foregoing that any desired adjustment may be obtained for dressing the edge either at right angles to the side of the stock, or at an angle oblique to the planes or faces of the sides of the stock.

My improved cutter head 7 is shown in the form of a rectangular body against the sides of which the knives 96 are clamped by means such as bolts 97. The knife edges 98 project over the sides, adjacent the sides to which the knives are clamped, and each side of the body 7 overhung by a. cutting edge, is provided with a filleted portion to prevent chips from wedging the knives away from the proper seat against said body by entering between the knives and said body at a point adjacent the knife edges.

A suitable guard 100 may be provided when the machine is being used for planing purposes. Furthermore, the table structure may be graduated, as indicated at 101, so

that a reading as regards the adjustment of said table may be visible at edge 102, of the side frame member 2.

It is believed that the device of my invention will be clearly understood from the foregoing description and while I have hereinshown and described one specific form of my invention, I do not wish to be limited thereto except for such limitations as the claims may import.

I claim V V 1. A combined planer and jointer comprising a rotary cutter, a planer feed mechprising a main frame, a rotary cutter journaled on said frame in a fixedrel-ation, a planer table earned by the mam frame be low said cutter, a supporting frame hingedly mounted on said main frame to be capable of upward swinging movement to a raised position, and a j'ointer bed mounted on said supporting frame to be supported in an operative relation when the frame is lowered and to be carried by the supporting frame as the same is raised to permit ready access to be had to the planer table.

3. A combined planer and jointer comprising a main frame, a rotary cutter journaled on said frame in a fixed relation, a planer table carried by the main frame below said cutter, a supporting frame, ahinged connection between one side of said supporting frame and the main frame arranged to permit the supporting frame to be raised in a swinging path, a jointer bed adjustably mounted on said supporting frame to be capable of relative adjustment to hold stock placed thereon at the proper height for operation by the cutter, means carried by the supporting frame to accomplish the desired adjustment of said jointer bed, the

Copies of this patent may be obtained for hinged mounting of the supporting frame arranging the parts in such relation that the supporting frame may be raised to carry the jointer bed to a relation beyond the main frame to permit more ready access to be mounted on the main frame below said cutter, means to adjust said planer table to the proper height, supporting frames on the upper part ofsaid main frame on each end beyond the cutter, a hinged connection between one of said supporting frames and the side of the main frame arranged to permit the hingedly mounted supporting frame to be raised to a position over one of the side portions of the main frame, jointer beds mounted on said supporting frames to be capable of adjusting movement thereon, independent means for adjusting the relative height of the jointer beds upon the supporting frame for the proper support of stock for operation by said cutters, and means to retain said hingedly mounted supporting frame in the raised relation to hold the jointer bed thereof raised to permit access to be had more readily to be planer table.

In testimony whereof I aiiix my signature in presence of two witnesses.
